DNS not allowing dynamic updates

I have been through all the standard settings that allow
dynamic updates to take place to the DNS database. All
seems to be in order. Still this is not occurring when I
move a workstation from one subnet to another. The
workstation ID is keeping the IP address that it was first
given by the DHCP server. The only thing that I have found
that our original consultant did was give a different SOA
on the primary and secondary DNS servers. Each has the
name of the server that is hosting our single DNS zone,
DC1 and DC2. Should there be only a single reference to a
SOA regardless if the second DNS server is for fault
tolerance purposes? The structure of our network is made
up of W2K servers and W2K Pro workstations, with CISCO
routers and switches.
 
If you are using an Active Directory integrated zone, then there is no primary or
secondary dns server. They are all equal and can record records/changes to dns zone.
If there is a primary and secondary, then there is only one SOA record on the primary
that the secondary would refer to by serial number to see if any changes have been
made in order to request replication. On the workstation that you moved try running
ipconfig /release and then ipconfig/renew to get new dynamic ip configuration and
then run ipconfig /registerdns. Running netdiag on it looking for any failed tests
may also be a good idea. There is also a win2000.dns newsgroup. -- Steve
 
Depending on where your DHCP service and DNS service sits, and how your DHCP
server is configured for DNS updates then check technet for DNSProxyUpdate
group. DHCP server may need to be be a member of group.
